To all LU/W770 it may concern:

'Be it known that I, JOHN M. CONLEY, a

I citizen of the United States, residing at Goiconda, in the county of Pope and State of Illinois, have invented a new and useful ire-Stretcher, of which the following is a specification.

Thisinvention relates to wire stretchers, and aims to provide a novel and improved device of that character.

It is the object of th present invention to provide a wire stretcher of uniqueconstruction, whereby its utility is enhanced.

Another object is to provide a wire stretcher which may be utilized for stretching a fence wirepast a post to which it is to 7 ing drawings, wherein Figure 1 is a side elevation of the improved wlre stretcher in use. F1g. 2 1s a similar .view showing how the structure is utilized in stretching the fence wires beyond the post to which they are to be secured.

Fig. 3 is a side elevation illustrating the useof the device as a jack or post puller. Fig. 4 is an enlarged 'fragmental view of the device. Fig. 5 is a cross sectional view taken on the line 5--5 of Fig 1. Fig. 6 is a plan view of the device as used in'the same capacity as shown in Fig. 2.

The stretcher includes a bar 6, through which are driven pins 7 to form studs upon the opposite sides of the bar. The pins or studs project substantially equal distances.

from the respective sides of the bar and are arranged in two series A and A parallel with and spaced from the edges of the bar. The pins or studs of the two series are in staggered relation.

A lever 8 has a fork 9 at one end straddling the bar 6. The width of the fork arms is such that the same will at all times contact with or ride upon at least two pins or studs, thus preventing the fork arms from Specification of Letters Patent. Pafggntgd B1311 28, 1916,

dropping between or interlocking with the pins or studs, and enablingfthe fork 9 to successfully ride along the bar.

- Pawls or dogs 10 have their butt ends fulcrumed upon pivot pins 11 secured through are arms of the fork 9 at the opposite edges of the bar 6. The pawls 10 are of U-shaped cross section so as to straddle the edges of the bar 6 and have the flanges 12 snugly engaging the sides of the bar to prevent the pawls from flexing to one side or the other. The pins 11 are engaged through the basal ends of the flanges 12. The flanges 12 are provided at the free ends of the pawls with thehooks 13 engageable with the respective pins or studs 7. The outer edges of the hooks 13 are curved to form cams 13 for causing the hooks to snap over the pins or studs 7. 1

The pawls 10 are spring pressed by-nieans of wire springs 14 having their intermediate portions coiled around the pins 11, each spring 14 having one of its arms engaged through the intermediate portion of the cor responding pawl 10, as at 15, and having its other end hooked around or engaged to a pin or rivet 16 secured through the arms of the fork 9 at the corresponding side of the bar 6. The springs l tend to swing the free ends of the pawls inwardly or toward the pins or studs 7, and the intermediate portions of the pawls hearing or riding against the edges of the bars 6, limit the inward movement of the hooks 13, so that the cams 13 will cooperate properly with the pins or studs 7. r The arms of the fork 9 are provided with outstanding apertured ears 17 intermediate the edges of the bar 6, and chains 18 are secured to the ears 17, and have terminal hooks 19. A chain 20 is secured to one end of the bar 6, the said end of the bar being preferably curved, as at 21.

In the use of the device as illustrated in Fig. 1, the end 21 of the bar 6 may be anchored to a post P by passing the chain 20 therearound and engaging the hook 20 at thefree end of the chain 20 with one of the links of the chain 20 after the said chain has been wrapped around the post. The chains 18 may then be passed around a fence clamp C and the hooks 19 engaged to the proper links of the chains 18, in which event the handle or lever 8 may be oscillated to stretch the wires W attached to the clamp (3, As the handle or lever 8 is oscillated,

the cams 13 of the hooks 13 Willcause the hooks to alternately snap over the pins or studs 7 of the two series A and A whereby 7 the lever 8 will be advanced along the bar 7 6to stretch the Wires W.

bar 6 remote from the end 21, may be set against the post P and hooks 22 engaged around the postP at that side opposite the Wires W, the hooks 22 having eyes 22 at the ends of their shanksfor engaging the proper pins or studs 7 for attaching the hooks to the bar 6. Thus, the hooks 22 Will resist the tendency of the bar 6 to swing around the post P,Ydue to thetension of the ires W, and the hooks 22 Will also assist in holding the bar 6 invplace against- Y the post;

Having thusdescribed the invention; what is claimed as new is In a device of the character described, a bar having studs projecting fromits sides and'adjacent its edges,a lever having a fork straddling the bar, and paWls of U-shaped cross section pivoted Within the forkat the In testimony that I claim the foregoing as my own, I have hereto aflixed my si-"gna;

ture in the presence of tivo' ivitnesses. V
